[Class 100 (i).] Delivery apparatus for printing-machines comprises a sheet-receiving tray P, Fig. 3 and a spare tray P placed beneath it, spring means being provided whereby the spare tray is raised to the place of the filled tray when the latter is removed. The trays are slid into position on guides 2 comprising inverted T-bars. Above one-half of the length of the guides 2 are inverted T-bars 3 and above the other half are T-bars 1. Fixed to the base 7 below the bars 1 and between the guides 2 are leaf-springs 8 which, when the tray P is moved beyond the bars 3, lift the tray until it abuts against the horizontal flanges of the bars 1. In this position, catches 6, Fig. 4, on leaf-springs 5 project through slots in the vertical flanges of the bars 1 and engage recesses 15 in the lateral members 16 of the tray so as to support the tray P. When the spare tray P<1> is moved into position beneath the tray P it is pushed upwardly by the springs 8 so that when the tray P is removed on to the bars 3, the spare tray moves automatically into sheetreceiving position. Members 11 form lateral guides for the sheets as they enter the tray and are hingedly-connected to the top of the bars 1 so as to swing out of the way when the tray is removed. Front stops 24 pivoted on an axis 23 are moved to permit of the removal of the tray P by the engagement of the tray sides 16 with rollers 21 connected by levers 20 to the axis 23.

Title: Improvements in the manufacture and production of magnetic materials
IPC: C22C33/02
Filed: 1931-09-23
Abstract: Magnetic compositions containing two or all of the metals iron, nickel, and cobalt, with or without other elements, for example molybdenum, vanadium, chromium, manganese, titanium, silicon, and aluminium, are made by consolidating and interdiffusing mixtures of finely divided metal powders under such conditions of temperature and pressure that, while alloying takes place to a certain extent, the product does not become homogeneous.  The heating, which may be at 600-1000 DEG  C., is preferably carried out in an inert or reducing atmosphere or in a vacuum; the time of treatment varies with the size of the particles and with the nature of the mechanical treatment. Metal powders obtained from carbonyls may be used, or in some cases coarse particles, turnings, or cuttings, and the products may be non-porous or porous.  Specifications 311,141 and 326,536, [both in Class 82 (i), Metals, Extracting &c.], are referred to.ALSO:Magnetic compositions containing two or all of the metals, iron, nickel, and cobalt, with or without other elements, for example, molybdenum, vanadium, chromium, manganese, titanium, silicon, and aluminium, are made by consolidating and interdiffusing mixtures of finely divided metal powders under such conditions of temperature and pressure that while alloying takes place to a certain extent the product does not become homogeneous.
